摘要: 环氧化植物油主要用作聚氯乙烯以及其它含卤素高聚物的增塑剂兼热稳定剂.以硫酸、硫酸钠、三氟化硼为环氧化的催化剂国内外研究较多[1,2],以酸性离子交换树脂为催化剂制备 环氧大豆油也有报道[3].目前,在环氧植物油生产上存在提高产品环氧值、降低酸值、改善色 泽、提高产品质量等技术问题.本实验采用非溶剂法,以杂多酸(盐)为催化剂,以甲酸和双氧 水生成的过氧甲酸为环氧化试剂,此法具有工艺过程简单、反应时间短、产品环氧值高、颜色浅、酸值低等优点.

Abstract: Some heteropoly acids were used as catalyst for epoxidation of soybean oil and corn oil by hydrogen peroxide and formic acid. Among them the CPW, i.e.[(C5H5)N-(CH2)15CH3]3PW12O40 was found to be the most active one. The epoxidized soybean oil and corn oil have epoxy value of 6.6% and 6.4%, respectively, with iodine value less than 6 g(I2)/100g.

Key words: epoxidation, soybean oil, corn oil, heteropoly acid
